It is good news that those Anglican parishes that are strongly opposed to homosexuality are forming a new movement. The Fellowship of Confessing Anglicans (FCA) was launched last year as a pressure group within the international Anglican communion, but only now is it trying to exert grassroots influence, raising awareness for its cause on the parish level. If it is successful, then it will be easy to identify the sexual politics of your local parish church. It will be impossible to deny that there is a church within the church, that division has become schism.

This is good news because honesty is better than dishonesty. The fact is that conservative evangelicals profess a different version of Christianity from other Anglicans. There are admittedly other divisions within Anglicanism, but this is the really big one. If opposition to homosexuality is a basic component of your idea of Christian truth, then you ought to be clear about this, and not cohabit with those who fudge the issue, or openly express disdain for your position.

Over the past 20 years or so we have seen huge amounts of dishonesty and evasion on this. The church's leadership has been trying to build a home on the fence. The liberals and the conservatives must both be accommodated, it has said: as long as both sides are still part of the same communion, then there is hope of reconciliation. A pious sentiment, surely? Well, the piety is laced with self-serving evasion and hypocrisy.

The fault lies with the liberals. Their complacency and cowardice have been breathtaking. In the 1990s, liberal Anglicanism ought to have asserted itself, and called for reform on sexual teaching. For the traditional teaching, that sex was for straight marrieds only, was out of sync with liberal opinion. Instead of achieving reform, the liberals allowed the conservatives to tighten the rules. Despite employing disproportionate numbers of homosexuals, the church was now more explicitly discriminatory against homosexuals than ever. But still the liberals shrugged, and assumed that enlightenment would soon prevail. The evangelicals would soon get over their homophobia and reform would come.

Liberal Anglicanism therefore became tainted by an acute hypocrisy. It became defined by open contempt for one of its own rules. The rule that priests should not be actively homosexual is a rule that liberals see as sub-Christian, heretical. Instead of demanding its repeal as a matter of urgency, and daring to pledge to leave the church if it was not repealed, they retreated, smugly superior, full of camp little Oxford jokes about how ghastly the evangelicals are.

My background is liberal Anglican, but I gradually realised that I couldn't have much respect for these people, whose liberalism was so timid, so political, so self-serving. I do not share the opinions of the evangelicals, but I can see that they are more honest: all they are saying is that this church has decided to proscribe priestly homosexuality, so let it stick by that.

The basic dishonesty of liberal Anglicanism is evident in the Telegraph today, in the form of Rev George Pitcher. Why can't we all get on, he asks, why can't the Evangelicals agree to disagree, but stay within the big tent? Why do they have to be so horrid about homosexuals, saying that they must repent? Why are they so sure they know the mind of God on this issue?

If Pitcher were serious about opposing discrimination he would leave a church whose official policy was discriminatory. Liberal priests of course reply that they are seeking reform from within. What a convenient position.

It is the liberals who are arrogant. They are so sure they know the mind of God on this issue that they think it legitimate to ignore the rules of their church, which must surely be on the verge of being reformed, because everyone they ever talk to agrees with them.

The big question for Christianity today is whether it is fully committed to liberal values, or whether it thinks that liberalism can be sacrificed to institutional authority. Pitcher follows his archbishop in loving to sound liberal, but ultimately putting the authority of priests and bishops first. This careful hypocrisy is admittedly very true to Anglican tradition, but that does not redeem it.

So let us hope for more honesty. The Church of England consists of two incompatible forms of Christianity. It is not pious to want this obscured, by spouting the old "broad church" rhetoric. It is dishonest. Let a new wave of honesty smash apart this rotten church with its homophobic legalism on one side, and its lazy-thinking smugness on the other.
